Brentford scored two goals in the final 10 minutes to come from behind and deny Watford victory at the Community Stadium.

Bryan Mbeumo slotted in a stoppage-time penalty to make it 2-1, minutes after captain Pontus Jansson had equalised with a header at the back post.

Watford led for an hour thanks to Emmanuel Dennis' first-half header but a late surge from Brentford was eventually rewarded.

Defeat means Watford remain just three points above the relegation zone.

Dennis, who has been directly involved in nine of Watford's last 12 Premier League goals, was left unmarked as he nodded in the opener against the run of play in the first half.

Brentford had controlled the first 20 minutes, coming close through Shandon Baptiste and Mbeumo but Watford goalkeeper Daniel Bachmann made several smart saves.

Joshua King's curling effort then struck the post, giving Watford their first corner of the match, and Dennis converted.

Watford looked set to take all three points home too but Brentford burst into life late on when Jansson got on the end of a curling cross to nod in the equaliser.

Brentford piled on the pressure as the game went deep into stoppage time and substitute Saman Ghoddos was brought down by William Ekong to set-up a dramatic finale.

Mbeumo kept his cool to send goalkeeper Bachmann the wrong way and the win moves Brentford up to ninth in the table for at least a night.

Afterwards, Bees manager Thomas Frank said: "It's crazy. This is what football is all about, these are the moments we are working so hard to try and achieve.

"The game against Leeds was cruel, conceding last minute and now we're scoring last minute. We have quite a lot of injuries, we are playing players out of position, and we go in there and we just attack. We didn't settle for a draw. Unbelievable mentality from the team.

"Mbuemo deserves a lot of praise. I think he was unplayable today. I've said before I have the world's best penalty taker in Ivan Toney and now maybe I have number two as well.

"All the game not everything was beautiful but we kept trying to play. In general we are giving away a set-piece and one transition chance against a team that has been one of the best offensive teams. They kept patience, fantastic.

"It's an unbelievable performance and getting three points with the injuries, we equalise in the 87th minute and still go for the win, that's crazy."
